When I ordered the thing I was a bit skeptical - what you can ask for 140 - large expected? Now I'm smarter and absolutely pleasantly surprised. First load, connected to the FIIO X5 (using the Stacking Kit), the Beyerdynamic T90 plugged and then just amazed! The amplifier has a recessed switch, so you can raise the gain by 16dB, which I did on the side so. Without it could possibly become scarce in some headphones. I have not yet tested the crossfeed function. Oh yes, duration about 12 hours, after which the machine switches off automatically. And the sound is also excellent and beautifully neutral. Good shots do not sound good and bad just. The processing is also very neat.
